You can perform reversible Work: stretching a spring - you can look at some old watches and see the mechanism. you can put electric current into a Capacitor.
It depends on spring energy or spring strength
The spring has been stretched. When the coils are squeezed together then the spring has been compressed.
Without a spring, the lock would never unlock. Therefore, a lock of a door required a spring.
Connect a mass to the bottom of the spring. (depending on the spring size, the mass will vary, the larger the spring the greater the mass u can use) Suppose you use a 100 g mass on a spring, measure the amount by which it stretches and record the data. Use hooke law to figure out the constant of the spring. K = m.g/x m = mass, g =gravity, x = stretch
in an adjacent coils ,the current flows in same direction so there is force of attraction shortening the coils.
The current passing through the spring will generate heat due to the electrical resistance of the metal. This heat could potentially cause the spring to expand or change its mechanical properties, leading to a change in the weight's position or the spring's behavior. Additionally, the magnetic field generated by the current may interact with the weight if it is magnetic, causing it to move.
When an electric current passes through a metal spring, it generates heat due to the resistance of the metal. This heat causes the metal atoms to vibrate more and the spring to expand. Once the current stops, the spring cools down and contracts back to its original size.
When electric current passes through a spring, the spring can become magnetized. The magnetic field generated by the current induces a magnetic field in the spring, causing it to act like a magnet. This magnetic property can be harnessed in various applications, such as in electromagnets or speakers.
Primary current is a flow to be measured that cannot be safely passed through the measuring device. A current transformer is used to provide a lower level, secondary current that can be passed safely through the measuring device. Primary current is measured as a secondary current, multiplied by the turns ratio in the current transformer.

Lightning is a DC current and it will pass through your body with devastating effect. Defibrillators use a DC current to restart/reset your heart if it has stopped or gone into fibrillation. So DC current is passed through your body.
yes it does
In the spring of 1774, parliament passed yet another set of laws, this time to punish the colonist for the troubles in Boston and elsewhere.
A ballistic galvanometer is used by electricians to measure an electric current. It is commonly used to test whether or not an electric current is present. A ballistic galvanometer consists of a meter that is attached to two probes, one positively charged and one negatively charged. This keeps the user from being electrocuted when an electric charge is present.
